Description
Technical field
The invention belongs to crop planting field, it is related to a kind of dedicated zinc-rich nutrient liquid of rice and for standing grain such as zinc-rich paddy rices
The method of graminaceous plant production.
Background technique
Zinc is one of necessary microelement of human body.Zn-ef ficiency is enhanced human immunity to growth in humans's development is promoted,
Influencing the physiological functions such as metabolism and the vision of vitamin A has irreplaceable role.
Solving the undesirable strategy of zinc nutrition at present mainly has medicament supplement and food supplement.Medicament supplement lacks rapid improve
Zinc human body Zn content significant effect, but there's no such thing as a totally safe medicine, and ideal effect cannot not only be reached by blindly taking zinc supplementation drug, or even be risen
To the effect run counter to desire, personal health is influenced.Food supplement is to improve underfed most desirable route, more edible richnesses
Zinc food can effectively improve zinc deficiency symptom, especially if the zinc content of staple food rice can be improved, so that it may reach steady in a long-term
Offer Zn-ef ficiency, be the optimization to food replenishment strategy.By breeding and Cultural practices, the zinc for improving the edible part of crop contains
Amount, is a kind of effective approach.
The zinc content of general rice is 10-15mg/kg.
Current material containing zinc fertilizer mainly has solid fertilizer and liquid fertilizer, but in view of solid fertilizer effect is poor, is easy to run off, and
Irreversible change can be generated to soil, so the present invention is to prepare a kind of liquid containing zinc nutrition, not only have zinc supplementation effect to crop,
And promotes crop yield, the infringement for resisting crop germ, fixed nitrogen, promotes precocious effect.
Mainly there are inorganic zinc (zinc sulfate, zinc oxide etc.) and coordination zinc (EDTA zinc network in the zinc source of zinc supplementation agent used at present
Mixture), but their disadvantages are obvious, and inorganic zinc source difficulty absorbs, and is easy to run off；It is difficult to degrade to be coordinated zinc, residual rate is high, toxic to plant
Effect.
Such as Chinese Patent Application No. CN201410037199.5, entitled rice zinc-rich nutrient agent and its preparation and it is used for
The method for producing rice rich in zinc, using the mixture of one or more of soluble zinc salt or zinc oxide as zinc source, zinc source
Hardly possible is absorbed, is easy to run off, and manufacture is easy to pollute soil at fertiliser granulates as zinc-rich nutrient agent, and utilization rate is low.
Summary of the invention
The deficiencies of present invention is to solve zinc source difficulty absorption in the prior art, be easy to run off, and one kind is provided with small molecule
The zinc salt of the polysaccharide sulfate of amount is prepared into the dedicated zinc-rich nutrient liquid of rice as zinc source, and is used for production rice rich in zinc,
The Zn content in rice can be dramatically increased, moreover it is possible to promote eary maturity of rice, improve yield.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of dedicated zinc-rich nutrient liquid of rice, the zinc source of the zinc-rich nutrient liquid is the zinc salt of polysaccharide sulfate, described
Zinc-rich nutrient liquid is formulated by the raw material of following mass percent:

In the starch-polysaccharides zinc sulfate of the chondroitin sulfate zinc salt of small-molecular-weight, the heparin zinc salt of small-molecular-weight and small-molecular-weight at least
It is a kind of.
A kind of method that the dedicated zinc-rich nutrient liquid of rice is used to produce rice, described method includes following steps:
The configuration of S1, zinc-rich nutrient liquid:
The zinc-rich nutrient liquid is formulated by the raw material of following mass percent: the zinc of 10%-45% polysaccharide sulfate
Salt, 1.5%-3.0% methionine, 1.5%-3.0% serine, 5%-8% glycine betaine, surplus are water, and raw material summation is
100%；
By the zinc salt of the polysaccharide sulfate of formula ratio, methionine, serine, glycine betaine and water stirring and dissolving to get zinc-rich
Nutrient solution；
S2, field spray:
Zinc-rich nutrient liquid is sprayed on to the different plot of paddy field, the field amount of application of zinc-rich nutrient liquid in Grain Filling
For 480g~500g per acre；
S3, water and fertilizer management is carried out, to get rice rich in zinc after rice is mature.
Preferably, spraying the zinc-rich nutrient liquid to rice leaf or/and soil.
It is furthermore preferred that spraying the zinc-rich nutrient liquid to rice leaf.
Preferably, in step s 2, the zinc-rich nutrient liquid is sufficiently stirred with 58~60 times of its weight of clear water molten
Field is carried out after solution again to spray.
Preferably, spray the zinc-rich nutrient liquid 2~3 times in Grain Filling, every time between be spaced 5~7 days.
The beneficial effects of the present invention are:
Zn-ef ficiency of the invention is absorbed by rice leaf, effectively facilitates Rice Photosynthesis, improves zinc-rich nutrient liquid
Absorptivity keeps plant strain growth in great numbers, is directly entered nutrition and microelement in rice body, participate in rice metabolism with it is organic
Synthesis, methionine, serine, glycine betaine etc. in formula, which are formed, point can promote rice high yield precocious, raising yield；Of the invention
The rice that method is cultivated is a kind of natural zinc-rich rice, and the absorption of human body utilization rate of this biological zinc is high, and the present invention can be mentioned obviously
Zn content in high rice is 3-5 times of general rice Zn content, and zinc content reaches 30.6-53.5mg/kg.
